SIGNAL-LANTERN.

SPECIFICATION forming part of Letters Patent No. 350,029, dated September 28, 1886.

Application filed December 31, 1885. Serial No. 187,231.

To all whom it may concern.-

Be it known that I, CHARLES H. ANGLE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Signal-Lanterns, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain improvements in signal-lanterns for railroads and other purposes; and it has for its object to provide a lantern by which a variety of colored signals may be instantaneously displayed, one at a time, as required. These objects I attain by the means illustrated in the accompanyin drawings, in which- Figure 1 illustrates a vertical sectional view of my improved lantern, and Fig. 2 a horizontal sectional view taken on the line :0 w of Fig. 1. Fig. 3 represents an enlarged detailed view showing the guides and the projections or buttons attached to the tubes and sliding in said guides.

The letter A indicates the base of the lantern, B the glass, 0 the guard, and D the up per section or top, which are all of the ordinary or any approved construction, and hence require no special description. The base plateE is raised slightly above the lower edge of the base A, so as to leave a space below said plate when the lantern is set down.

The letter F indicates the lamp, which is socured to the said plate at its center, and which is also of the ordinary description. Surrounding the lamp, and inside of the lantern, are arranged two movable tubes of transparent glass or other material of different col0rsred and green, for instance. These tubes are of different diameters, and are located one within the (No model.)

other, the two being parallel. They are each mounted on a wire frame, (indicated by the letters G and H, respectively.) These frames pass through openings in the bottom or base plate, the lower portions, 9, forming handles by which they may be moved up and down to elevate or depress the tubes.

In order that the tubes may move truly and parallel with each other, the upper portions of the frames are arranged to move in vertical guides I, which are fastened to the bottom or base plate, and extend nearly to the upper end of the respective tubes when the same are down. When the tubes are up, the handles set in recesses under the bottom of the lantern. The tubes are provided with projections or buttons 13, which slide in the vertical guides, thus keeping the tubes truly concentric.

Touse the lantern it is simply necessary to elevate the tube having the desired color, so as to surround the light. When both tubes are down, a white light will be shown.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, 1s

The combination, in a lantern, of the movable concentric tubes of transparent differentlycolored material, the vertical guides, and the projections or buttons attached to the tubes and adapted to slide in said guides, and the frame extending through the bottom of the lantern and secured to the tubes. whereby they may be moved up and down, substantially as specified.

In testimony whereof I affixmy signature in presence of two witnesses.

CHARLES H. ANGLE.
